KYB 5530020 Suspension Shock Absorber - Rear

KYB Gas-a-just Rear Shock for EcoSport

The KYB Gas-a-just 5530020 is a rear suspension shock absorber for the 2018-2021 Ford EcoSport. It is built as an OE monotube replacement to restore original ride control, with a design that separates hydraulic response from high-pressure gas support for consistent damping.

Gas-a-just Product Line Details

KYB Gas-a-just shocks use a monotube layout with two working chambers. The hydraulic piston and valve area handles normal road response, while the nitrogen gas chamber with a floating piston adds immediate firmness when driving conditions demand more control. For a Ford EcoSport rear shock replacement, this setup supports stable handling without changing the vehicle’s original suspension layout.
